The LED indicators on the front panel indicate status, configuration, and activity: 

  Flashes when the modem is transmitting data to another modem. 

 Flashes when the modem is receiving data.  

 Lights when the modem detects a valid carrier signal from another modem. It is on when the 

modem is communicating with the other modem, and off when the link is broken. 

 Lights whenever the modem is set for or connects using the V.90 or V.92 protocol. 

The actual connection speed depends on ISP server capabilities and line conditions. 

 Lights whenever the modem connects using the V.34 protocol. 

 Lights when the modem connects using the V.32bis protocol. The modem can 

connect at lower than V.32bis speeds, but no speed indicator lights during the connection. 

 Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a 

call. Flashes when the modem pulse-dials.  

TR – Terminal Ready. 

Lights when a communications program is using the modem. It means the modem is ready for an 

outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes 
off, a connected modem will also disconnect.  

 Lights continuously when the modem is in V.42 error correction mode, and flashes when 

compression is activated.  

 Lights when the modem is in fax mode.  

Note: 

When you turn on the modem, the protocol indicators flash briefly as the modem does a self-test, after which the 

56 indicator lights. After a call, the indicator for the protocol used in the connection remains lit until another call is 
made or the modem is reset. If you connect at a rate under 14,400 bps, all protocol indicators remain off after the 
connection is broken, even though the modem is still turned on.
